This is a whole new world of fingerprint sensors. In-display fingerprint sensors are the way of the future, and they’re slowly taking place of the capacitive sensors we all know and love.
These new in-display units are beneficial because they don’t take up as much room inside the phone, and don’t require the rear design of the phone to be changed in order to accommodate the sensor.
The fingerprint sensor is designed to work with a screen protector — but it’s not a guarantee with every one you find. Only screen protectors from OnePlus and its partners are guaranteed to work.
The OnePlus 6T comes with a pre-installed plastic screen protector out of the box, so we know that the fingerprint sensor will work with this extra layer of plastic.
What OnePlus can’t guarantee, though, is that any random screen protector you buy online will work the same way. Right now OnePlus is saying that you can only use screen protectors that it sells directly, or from yet-to-be-named partners that will certify that their protectors work with the new sensor.
Thankfully OnePlus is quick to offer its own screen protectors, with a quality tempered glass version that retails for just $21. If you want to wait for your preferred brand to release a screen protector for the phone, you at least have the protection of the pre-installed protector, which is actually quite good for a basic plastic sheet.
